The disc brake pads have been used as reinforcing materials for the brake pads since the beginning of the asbestos, because of their high strength and high temperature resistance, the requirements of the brake pads and clutch pads and pads can be met. This fiber has a strong resistance to Zhang, can even be matched with high-grade steel, and can withstand the high temperature of 316 ℃. More important is the relatively inexpensive asbestos, which is extracted from the pumice ore, which has been widely found in many countries.Brake Pad

Asbestos accounts for $number in the proportion of asbestos-type brake pads, but it is now found that most asbestos is potentially harmful, asbestos has been confirmed by the medical profession is carcinogenic substances, its needle-like fiber is easy to enter the lungs and stay, resulting in stimulation, can eventually lead to lung cancer, but the incubation period can be up to 15-30 years, so people often do not realize the harm caused by asbestos. As long as asbestos fiber is fixed by the friction material itself will not be harmful to the health of staff, but when the stone fiber along with braking friction to form the brake dust emissions, it may become a series of health-affecting causes.Brake Pad

According to the American Association for Occupational Safety and Health (OSHA) tests, every time a conventional friction test is carried out, the brake pads produce more than millions of of the asbestos fibres emitted into the air, and this fiber is much smaller than the human hair, which is invisible to the naked eye, so one breath may suck up thousands of asbestos fibres while people are unaware of them. Similarly, if the air duct is used to blow the brake dust from the brake drum or the braking component, it can also blow the countless asbestos fibres into the air, which will not only affect the health of the working technician, but also cause health damage to any other person present. Even some very simple operations such as: Hammer the brake drum to make it loose, so that the internal braking dust out, also can produce a large number of asbestos fiber floating in the air. What's even more worrying is that once the fiber floats in the air for hours, then they stick to the clothes, the desktop, the tools and everything you can think of on the surface of the object. Whenever one encounters agitation (such as cleaning, walking, and air flow using pneumatic tools), they will again float into the air.Brake Pad
